Why this matters
First thing AI reads
Title and meta description are the first signals AI uses to understand your page. Wrong or missing = AI misrepresents your product.
Canonical prevents confusion
Without a canonical URL, AI might see duplicate versions of your page and not know which to cite. One tag prevents this.
Social sharing = AI signals
OG tags control how your page looks on social media. AI also uses these for previews and summaries.

Frequently Asked Questions
How do I check the meta tags of a website?
Enter any URL in our Meta Tag Checker above. We fetch the page and extract the title tag, meta description, canonical URL, and viewport tag. You'll see each value, its character length, and whether it's within recommended limits.
What is a good meta description length?
Google typically displays 150-160 characters of a meta description. Keep yours under 160 characters to avoid truncation. More importantly, make it specific and factual — AI extracts meta descriptions when describing your product.
What meta tags are important for SEO and AI?
Title tag (under 60 chars), meta description (under 160 chars), canonical URL (prevents duplicates), viewport (mobile-friendly), and Open Graph tags (og:title, og:description, og:image) for social sharing and AI previews.
What is the difference between meta title and H1?
The meta title appears in browser tabs and search results. The H1 is the visible headline on the page. They can be different, but should be closely related. AI uses both to understand your page content.
How do I check my Open Graph tags?
Our Meta Tag Checker shows OG tags alongside standard meta tags. You can also use our dedicated OG Tag Checker at /og-checker for a more detailed preview of how your page looks when shared on social media.
